Ulnar Artery Aneurysm in a 6-Month-Old: A Case Report.

Abstract

Pediatric ulnar aneurysms are rare and, unlike their adult counterparts, cannot be explained by repetitive trauma to the palm. A small number of case reports describe diagnostic difficulty with these lesions and different treatments. We present the case of a 6-month-old with an ulnar artery aneurysm of unknown cause. The diagnosis was supported with magnetic resonance imaging, and the lesion was resected. Because the hand remained well perfused, the ulnar artery was not reconstructed. Although the early result was good, the long-term outcome of this approach is unknown.
